Nice detail in the blacks, sharp,HA,wing position,BG.
In a perfect world, the perch is perhaps bigger and more prominent than desired. Two small changes might downplay that. Crop up a bit form the bottom and burn it in more so that it doesn't compete so much with the bird.
Good pose, and I love the green eye against the orange . I made a few enhancements, just for practice: Slimmed and darkened the perch, rotated
CW, opened shadow details under the wings a little, and muted the background. Nice colors in the background, but to my eye they compete with the subject.
Very nice image. I find nice details on the original image posted and in my opinion I don't see the repost realistic as there are relatively top lights. Sharpness and wing stretch is cool.
